History

In 60 FC, Manon's husband, three-time Gundam Fight victor Gentle Chapman, returned to the Gundam Fights in his new John Bull Gundam to try and reclaim the rule of the orbiting colonies in the name of Neo England. Admired by the younger fighters for his skill, Chapman went undefeated for some time in his matches, and struck his opponents with ease by using his Gundam's long-range weapons. However, the first-hand account of George de Sand's defeat at Chapman's hands hinted that Chapman was no longer the proud warrior that he used to be - a series of strange occurrences led to the Neo France Fighter losing his advantage and being beaten into submission by the John Bull Gundam.

Investigating that event, Neo-Japan fighter Domon Kasshu challenged Chapman and was invited to dinner. Despite a confrontation between the two, Manon, pointed out their similarities and suspected Chapman that liked Domon as well. After dinner, Chapman accepted Domon's challenge and summoned his Gundam. After a few blows were exchanged, Domon appeared to have the upper hand, only for a mysterious, sensor-jamming fog to fill the battleground and unknown Mobile Suits who assaulted Domon. As Chapman pressed his advantage, Rain Mikamura discovered a hidden control room, and uncovered the truth behind Chapman's victory streak in the 13th Gundam Fight: Manon, in a desperate bid to support her husband without his knowledge, was using devices to create the fog and remotely command a squadron of MET6-MS Casshings- mechs similar in design to her husband's Gundam - in order to confuse opponents. Manon had also given Chapman special mental stimulants to help him see through the artificial fog.

With their secrets revealed, Manon and Chapman defended their actions against an irate Rain and Domon; Chapman had become a hero and a symbol of pride among the people of Neo England, but the stress of three consecutive Gundam Fights had left him in a weakened state. To continue to uphold his legend and maintain hope among the colony, Chapman had to resort to cheating to keep up with his new opponents. Nonetheless, Chapman was ultimately defeated by Domon after he started to suffer the side effects of the mental stimulants during their battle. With his body finally at its limit, and revealing he had known about her deception the entire time, Chapman died in Manon's arms as Domon and Rain looked on, and warned the latter about suffering the same fate in hopes that they could avoid it themselves.
